Studies of B0-B̄0 mixing properties with inclusive dilepton events

Aurelio Bay, Tagir Aushev, Sun Hee Kim, Ji Hyun Kim, Donghyun Kim, Sanjeev Kumar, Jing Li

We report a precise determination of the Z0-B̄0 mixing parameter Δmd based on the time evolution of same-sign and opposite-sign dilepton yields in Y(45) decays. Data were collected with the Belle detector at KEKB. Using data samples of 29.4 fb-1 recorded a ...

Mel-Cepstrum Modulation Spectrum (MCMS) Features for Robust ASR

Hervé Bourlard, Hemant Misra, Vivek Tyagi

In this paper, we present new dynamic features derived from the modulation spectrum of the cepstral traje ctories of the speech signal. Cepstral trajectories are projected over the basis of sines and cosines yie lding the cepstral modulation frequency resp ...

Fourier spectra of radially periodic images with a non-symmetric radial period

Isaac Amidror

It has been previously shown that a radially periodic image having a symmetric radial period can be decomposed into a circular Fourier series of circular cosine functions with radial frequencies of f=1/T, 2/T, ..., and that its Fourier spectrum consists of ...

On the Wold decomposition of discrete-time cyclostationary processes

Giancarlo Ferrari Trecate

The Wold decomposition of discrete-time CS (cyclostationary) processes into regular and predictable component is considered. Using the properties of the zeros of linear periodic systems it is shown that the predictable component consists of a linear combin ...

The Fourier-spectrum of circular sine and cosine gratings with arbitrary radial phases

Isaac Amidror

The Fourier spectra of circular gratings having sine or cosine radial profiles are derived, and their particular properties are discussed. These results are then extended to the most general form of circular sinusoidal gratings, namely: circular sine or co ...

Low-power CMOS, analog transient-stability-simulator for a two-machine power-system

Christian Enz

This paper presents a low-power analog simulator for the transient stability of a two-machine power system. The simulator is implemented in a standard digital CMOS process. Its building blocks are: sine shaper, transconductor with extended linear range, an ...

Measurement and Modeling of the Dynamic Behavior of Ag/Bi(2223) Superconducting Tapes

Martin Hasler, Bertrand Dutoit

Measurements of Ag/Bi(2223) superconducting tapes have been performed between dc and 30 KHz for under and upper critical currents, up to 2 or 3 times i(c). A fast power amplifier (100A 30KHz) has been specially built for pulsing such currents in the sample ...
